ARM64: dts: meson-gxl: fix Mali GPU compatible string

2018-08-24T11:06:52Z

[ Upstream commit 1c38f4afd5d40234b67635b3c608a4093be04b96 ] meson-gxl-mali.dtsi is only used on GXL SoCs. Thus it should use the GXL specific compatible string instead of the GXBB one. For now this is purely cosmetic since the (out-of-tree) lima driver for this GPU currently uses the "arm,mali-450" match instead of the SoC specific one. However, update the .dts to match the documentation since this driver behavior might change in the future.

ARM64: dts: meson-axg: fix ethernet stability issue

2018-08-24T11:06:52Z

[ Upstream commit 6d28d577510f1a51f7ffbe830fdbf42077e0058b ] Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to suffer from the kind of stability issue. Doing an iperf3 download test, we can see a significant number of LPI interrupts on the tx path. After a short while (5 to 15 seconds), the network connection dies. If using rootfs over NFS, the connection may also break during the boot sequence. We still don't have a real explanation for this problem so let's disable EEE once again.

arm64: Avoid flush_icache_range() in alternatives patching code

2018-08-24T11:06:52Z

[ Upstream commit 429388682dc266e7a693f9c27e3aabd341d55343 ] The implementation of flush_icache_range() includes instruction sequences which are themselves patched at runtime, so it is not safe to call from the patching framework. This patch reworks the alternatives cache-flushing code so that it rolls its own internal D-cache maintenance using DC CIVAC before invalidating the entire I-cache after all alternatives have been applied at boot. Modules don't cause any issues, since flush_icache_range() is safe to call by the time they are loaded.

arm64: dts: uniphier: fix widget name of headphone for LD11/LD20 boards

[ Upstream commit 86676c4685f774d818f7a6c401c925bbf2a92903 ] This patch fixes wrong name of headphone widget for receiving events of insert/remove headphone plug from simple-card or audio-graph-card. If we use wrong widget name then we get warning messages such as "asoc-audio-graph-card sound: ASoC: DAPM unknown pin Headphones" when the plug is inserted or removed from headphone jack.

arm64: make secondary_start_kernel() notrace

[ Upstream commit b154886f7892499d0d3054026e19dfb9a731df61 ] We can't call function trace hook before setup percpu offset.

arm64: dma-mapping: clear buffers allocated with FORCE_CONTIGUOUS flag

2018-08-24T11:06:44Z

[ Upstream commit dd65a941f6ba473a5cb9d013d57fa43b48450a04 ] dma_alloc_*() buffers might be exposed to userspace via mmap() call, so they should be cleared on allocation. In case of IOMMU-based dma-mapping implementation such buffer clearing was missing in the code path for DMA_ATTR_FORCE_CONTIGUOUS flag handling, because dma_alloc_from_contiguous() doesn't honor __GFP_ZERO flag. This patch fixes this issue. For more information on clearing buffers allocated by dma_alloc_* functions, see commit 6829e274a623 ("arm64: dma-mapping: always clear allocated buffers").
